Abstract

"MéTODO PARA PURIFICAR UM COMPOSTO DE NIóBIO E/OU UM COMPOSTO DE TâNTALO ALTAMENTE PURO". Um método de purificação para produzir um composto de nióbio e/ou um composto de tântalo de alta pureza, caracterizado pelo fato de compreender a formação de um composto de nióbio e/ou de um composto de tântalo pelo uso de um cristal obtido por cristalização de uma solução contendo nióbio ou tântalo, ou de um fundido ou de um filtrado da mesma, e separação de um composto de nióbio e/ou um composto de tântalo de alta pureza pelo uso da diferença de solubilidade entre eles. O método de purificação permite a purificação de um composto de nióbio e/ou de um composto de tântalo para um produto de alta pureza com um procedimento mais fácil e mais simples em um custo reduzido."METHOD FOR PURIFYING A NIOBIO COMPOUND AND / OR A HIGHLY PURE TEST COMPOUND". A purification method for producing a niobium compound and / or a high purity tantalum compound comprising the formation of a niobium compound and / or a tantalum compound by the use of a crystal obtained by crystallization of a solution containing niobium or tantalum, or a melt or filtrate thereof, and separating a niobium compound and / or a high purity tantalum compound by using the solubility difference between them. The purification method allows the purification of a niobium compound and / or a tantalum compound to a high purity product with an easier and simpler procedure at a reduced cost.
